Question

according to hooke's law if stress is reduced to one third the ratio of stress strain will be ?​

Answer 1

Answer:

According to Hooke's law of elasticity, if stress is increased, the ratio of stress to strain remains constant which is additionally referred to as Young's modulus. So, the correct answer is “Option B”.

Explanation:

Answer 2

According to hooke's law, if stress is reduced to one third;

the ratio of stress and strain will be 1 : 3

• Hooke's law states that "the strain of the material is proportional to the applied stress within the elastic limit of that material".
• Therefore, stress ∝ strain

                          stress = y(strain) {where 'y' is the constant of      

                                                          proportionality}

                          y = stress/strain

• y is known as the young's modulas of elasticity.
• Now if, stress is reduced to one third of the original;

                   y = 1/3

                   y = 1:3
